GIN-RIB.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed December 13, 1905. Serial No; 291,605.

1'0 and w/wm, it may concern:

Be it known that I, FRANcrs DANIEL ALL- GOOD, a citizen of the UnitedStates, residing at Thurmon, in the parish of Claiborne and State ofLouisiana, have invented a new and useful Gin-Rib, of which thefollowing is a specification.

This invention relates to ribs for cottongins; and the object of theinvention is to prevent the ribs from springing apart or spreading atthe points where the teeth of the saws pass between them, thus causingthe cotton to become packed between the ribs, and thereby not onlystraining and injuring the latter, but also permitting the passage ofseeds and foreign material which should be separated from the staple.

Further objects of the invention are to simplify and improve theconstruction and operation of the ribs.

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations, and modifications within the scope of theinvention may be made when desired.

In the drawings, Figure 1 is a vertical sectional view taken through thebreast of a gin formed with the improved ribs of this invention. Fig. 2is a plan view showing a portion of the breast. Fig. 3 is a perspectivevigw showing the upper end of one of the r1 s.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

1 2 are the cross-bars upon which a plurality of ribs 3 3 are mounted inthe usual manner, as by means of screws 4, to form the breast of thegin.

5 is the shaft carrying the saws 6 6.

The ribs are provided near their upper ends and closely adjacent to thepoints Where the teeth of the saws pass between them withlaterally-extending lugs 7 7, having square-faced vertical ends 8, that.abut upon each other, so as to positively prevent the ribs fromspringing laterally or from being spread in a lateral direction. Theunder sides or edges of these lugs present shoulders 9 at right anglesto the sides of the ribs, so that the passage of the fiber between theribs will not be obstructed. The under sides 9 of the lugs 7 are locatedin a planeparalleltoa tangent to the periphery of the saws 6. The upperedges of the lugs 7 may be beveled, as shown at 10.

By reason of the construction described springing or spreading of theribs is positively prevented, and clogging or packing of the gin-breastis thus practically prevented, thus not only preventing the passage ofseeds and trash between the ribs, but also preventing the injury to thelatter resulting from the springing or spreading and greatly increasingthe life of the rib.

Having thus described the invention, What is claimed is- In a cotton-ginhaving circular gin-saws,

ribs located between the saws and having laterally-extending lugs, saidlugs having square-faced vertical ends, the ends of the lugs of one ribabutting against the ends of the lugs of the adjacent ribs, the underedges of said lugs being located in a plane parallel to a tangent to theperiphery of the saws.

In testimony that I claim the foregoing as my own I have hereto afl'iXedmy signature in the presence of two Witnesses.

FRANCIS DANIEL ALLGOOD.
